Thanks, Rowan, for the clarification! And no, this is not my primary
question. At the risk of irritating everyone, here are the questions I need
answered:
1) Is there not any way to first iterate through the default properties and
then iterate through *only the dynamic properties* ?
zend_object->properties appears to contain ALL properties if the object has
a single dynamically-assigned property. If so, please advise? If not,
please confirm?
2) Will the code below ALWAYS return the properties in the same sequence?
E.g., if I am iterating through N objects of type MyClass, will each
instance iterate the properties in the same order?
3) Will the code below ALWAYS iterate over default properties (i.e.,
"sealed" properties, those explicitly defined by class definitinos) FIRST
and then iterate any dynamically assigned properties?
CODE:
zobj = zend_objects_get_address(*val TSRMLS_CC);
if (!zobj->properties) {
php_printf("***No dynamic properties!\n");
} else {
php_printf("***we got dynamic properties...sadly, this will
also iterate through default properties too\n");
zend_hash_internal_pointer_reset_ex(zobj->properties, &pos);
while (zend_hash_get_current_data_ex(zobj->properties,
(void **) &value, &pos) == SUCCESS) {
if (zend_hash_get_current_key_ex(zobj->properties,
&key, &key_len, &num_index, 0, &pos) == HASH_KEY_IS_STRING) {
if (zend_check_property_access(zobj, key, key_len-1
TSRMLS_CC) == SUCCESS) {
zend_unmangle_property_name(key, key_len - 1,
&class_name, &prop_name);
php_printf("dynamic property is %s, key_len is
%d\n", prop_name, key_len);
}
}
zend_hash_move_forward_ex(zobj->properties, &pos);
}
}
